Assessment Comments

Four stream use assessments in 1990 and fish tissue monitoring in 1996.

Basis for Assessment

Continue to use assessment of support of the Class B(WW) aquatic life uses developed for the 1996 report (=FST).   Results of fish tissue (RAFT) monitoring in 1996 show all levels of contaminants less than 1/2 FDA action levels, thus suggesting full support of the fish consumption uses (RAFT samples collected at Pammel State Park).   These results show an improvement over RAFT sampling in 1991 which showed levels of chlordane > 1/2 the FDA action level.
